Of course! You can switch between plans at any time. There are no penalties for downgrading. If you decide to change your plan, prorated billing will be applied. Simply meaning, you will only be charged for the actual time you were subscribed to your previous plan, and the 'unused' time will be credited to your account. This credit will be applied to applicable future billings. Your new plan will also be prorated from the time you subscribed to it, until the end of your current billing cycle, which normal billing will then occur.
